Hi guys,

Just a quick question, which side of this wiring diagram should the positive 5V be hooked up to?



The top line or the bottom line? or does it not matter as they will be wired in parallel?

Also, shouldn't the resistor be in front of the LED instead of behind it?
Fast help appreciated +
Thanks in advance.

The 5v is hooked up to both the top and bottom. The resistors can be put before or after but usually I put them before the LED.

I know the 5v goes to both LEDS.
Shouldn't one side of the wiring diagram have a ground?
like so:

All 4 LED will be running of 1 5V source.

EDIT: Thanks DennisC, I read too quickly.

That didn't work, None of the LED's are getting current.

Resistors are inline before the first LED on each side. Everything is wired up as per the diagram.

Any help appreciated.

Your 5V line is on the left of all components, the ground is on the far right (the node just beside R = 56 ohms).

Thanks very much, I knew there had to be a ground.

Will report back with the results.

Are you sure you have the LED's hooked up the right way? The long lead is positive, I think.

Still no good, no current to any of the LEDS.
All are wired with the Long leg as positive, short leg as negative.

Heres the best I could do with my phone.
The resistors as on the left in front of the left hand LEDS.
